Alien life in space is possible, says SETI astronomers


The existence of primitive alien life in planets within the Milky Way galaxy is 100% possible as scientific evidence suggests. SETI (Search for Extraterrestrial Intelligence) astronomers Dan Werthimer and Seth Shostak told the US congress on May 23 that the outer space is “teeming with primitive life.”

aliensIn Werthimer’s written testimony he said that life and conditions necessary for life to exist can be seen within our galaxy and perhaps within our own solar system. Dr. Werthimer and Dr. Shostak said that the abundance of planets across the Milky Way galaxy roughly one trillion suggests that our universe might also be abundant with both intelligent and primitive life.

The astronomers presented evidence that suggests that primitive alien life in our own solar system is possible. Jupiter’s moon Europa might have the possibility of life. It is believed to have oceans below its uppermost layers of ice.

The purpose of their presentation in the House Committee is to secure further funding to support their continuous study and search for alien life in outer space. The pair said that developing and upgrading the tools and technologies like the Arecibo telescope-the largest radio telescope in the world, will greatly help identify distant civilization. There could be signals from extraterrestrial civility that is now reaching our planet but it is impossible to discover these signals with old SETI projects said the pair.

The US is will soon be overwhelmed by other countries, with China currently developing a radio telescope which measures 500 meters in diameter (larger than Arecibo). Dr. Werthimer said China may soon surpass SETI’s research capabilities and become the world’s preeminent prime radio telescope.

Time Travel and Alien Visitors: Are They Possible?


Steven Hawking once made a public announcement that he was going to hold a party for time travelers. He made the announcement public so that any future historians who might live in a world that time travel is possible would know. Unfortunately, no one showed up. Time traveler possibly got the wrong date. Well, maybe time travel is not easy in any world.

The common problem with the future is that no one is certain about it. No one can tell what catastrophes might drastically alter the world. There is a possibility that humanity will start from scratch in the future, such as reinventing the wheel. Given that humanity will be starting from a better place than primitive ancestors, a simple paper invitation to uncertain party could be destroyed easily and difficult to recover.

If people in the future want to time travel in this time, it could be possible that future people are in such a bad state that they need to revitalize the race with DNA of the past. One thing to ponder is the genetic material compatibility. It is likely possible that people from the future have not evolved because they choose to travel back in time for genetic materials.

Time travel is a very complex subject and there are many factors to be perfected to travel to the exact time if, and only if, time travel is real. The actual time travel is the removal from one time to another without travelling across the vast space. Now, this concept of time travel poses problems. Earth rotates on its own axis and revolves around the sun. Earth is part of the Solar System, and the Solar System is orbiting the galactic core. Universe continues to expand. These factors have a lot of vectors and velocities to consider just making a temporal trip of even a few hundred years to get a specific target.

Another thing about time travel is that if anyone could travel in time, any change he makes in the existing time-line causes a branching of timelines to occur. Now, this poses another question. How to travel the correct branch to get home?

Extraterrestrials and Conspiracy Theories Over Mars


Our own planet Earth is full of life, and everyone is allowed to live freely. Our planet has the ability to make things live as well as those in the solar system and in other galaxies. Another planet that has been attracting the attention by scientists and other discoverers is Mars. This red planet is invaded by humans for so many times just to prove if there are other beings such as Aliens living in.

Unfortunately, not all people are given the opportunity to personally visit this planet and many conspiracy theories have emerged that strongly linked the government. There are reported claims that what governments describe as extraterrestrials in such planet is no other than a fake and a conspirative one. Critics maintain that governments love to use these terms in order to hide something they would not want to reveal to the public. Conspiracy seems to be lurking in governmental aims.

Intelligent agencies are avoiding to have leaks about extraterrestrials or aliens as much as possible. They continually contend that such information would result in public panics once proven. Nevertheless, the universe is still not fully studied. Perhaps, there are still many things and beings out there wandering, and science may not always be there to help us explain what is happening.

Current study increases the possibility of extraterrestrial life


There were more planets or exoplanet discovered according to a research published on the journalNature.

The new study estimated over 160 billion planets that were existed with corresponding stars in our Galaxy which was led by the Institute of Astrophysics.

According to the new study, every star in our Galaxy – or even a star in the sky we see – contains 2 or more revolving planets. Even there is only 0.01 percent of those billions of planets are inhabitable then we are not alone in our Galaxy.

More planets are expected to be discovered through the help of the Kepler Space Observatory that was launched for probe purposes in 2009.

“We conclude that stars are orbited by planets as a rule, rather than the exception.” researchers said.

We should colonize Mars according to Stephen Hawkins


Professor Hawkins showed in BBC Today programme saying that we should colonize mars but beware of alien encounters.

He also answered some public questions concerning humanity’s destiny to live in outer space.

His latest book “George’s Secret Key to the Universe“ was an explanation for the next generation who would aim beyond our knowledge and expand to other Galaxy.

Hawkins has been advising us of reaching the stars as he would always speak about future intergalactic humanity.

In 2009, he was the first to experience Zero gravity on a sub orbital space flight which cost £100, 000.00. He justified the cost.

“Many people have asked me why I am taking this flight. I am doing it for many reasons…First of all; I believe that life on Earth is at an ever-increasing risk of being wiped out by a disaster such as sudden nuclear war, a genetically engineered virus, or other dangers…I think the human race has no future if it doesn’t go into space. I therefore want to encourage public interest in space.” he justified.

In Today programme, Hawkins was asked about the subject’s concerns. “Do you think the human race will survive all potential disasters and eventually colonise the stars?”

Hawkins replied, “It is possible that the human race could become extinct, but it is not inevitable…I think it is almost certain that a disaster such as nuclear war or global warming will befall the Earth within a thousand years.”

This is one factor why cosmologist and theoretical physicist in Cambridge University would like to colonize Mars.

“It is essential that we colonise space. I believe that we will eventually establish self-sustaining colonies on Mars, and other bodies in the solar system, although probably not within the next 100 years.”

Hawkins encourages cosmologists and theoretical physicist to expand beyond our Galaxy.

He said, “I am optimistic that progress within science and technology will eventually allow humans to spread beyond the solar system and out into the far-reaches of the universe…The discovery of intelligent life elsewhere in the universe would be the greatest scientific discovery ever. But it would be very risky to attempt to communicate with an alien civilisation…Fleshing out the possibilities of alien interaction, Hawking went on: “If aliens decided to visit us, then the outcome might be similar to when Europeans arrived in the Americas. That did not turn out well for the Native Americans.”

The upcoming birthday of Hawkins in January 8 will be hosted by Cambridge University Centre of Theoretical Cosmology giving public symposium as a tribute to a professor who has 2 years to live after he was diagnosed in 1963 to a form of motor neuron disease.

Hawkins was a great contribution in science; he is also the one who changed the perception of our knowledge about universe through selling books which are best-selling. He is a family man and has 3 children and 3 grandchildren.

Proposed New Planet-Classification Scheme in Search for Extraterrestrial Life


Astronomers have found over 2,000 planets orbiting distant stars with the use of Kepler space telescope. The number is not that bad considering most of the people only know eight planets in the whole universe; all of them in the nearby Earth. Although, Kepler’s objective is not to pile up numbers but to search for worlds with likelihood to Earth where alien life is possible. Those discovered planets could even explored more if more sophisticated telescopes are invented.

However, the search for life from the distant stars won’t be easy even with the use of advanced telescope. So, the key to make it easier is to choose the best possible targets. That is the reason why environmental scientist Dirk Schulze-Makuch of Washington State University, together with nine other colleagues, has proposed a new way to classify distant planets easier through a new paper in the journal Astrobiology.

They have actually proposed two elaborate and systematic ways which were designed to let observers cut their searches in two different methods. The first method is what they call Earth Similarity Index or ESI. It measures the closeness of extraterrestrial world to Earth in terms of temperature and size. Biologists believe that it is important to know the temperature of the alien world because liquid water plays an important role for life as everybody knows it. Nutrients easily dissolve with water to circulate to every part of organism. Blood without stuff dissolved in it is just water after all.
Meanwhile, the size of the planet is equally important because as scientists have been observed, planets that are too small might not have sufficient gravity to hold on to its atmosphere just like Mars. On the other hand, if the planet is too big the atmosphere might have pulled by too strong gravitational force, which could lead to crushing pressure at the surface. Scientists estimate that an alien world that has more than five times bigger than Earth could bring some problems. As of today, only Earth is capable of holding life. This make researchers think that the alien world should look like Earth as much as possible.

The second method is called the Planetary Habitability Index or PHI. It included planets with “stable substrate” which means a solid surface protected by an atmosphere. It also examine energy source, chemical environment capable to form complex molecules and the existence of a liquid solvent (not necessarily mean water). Schulze-Makuch said that when PHI is applied, moon of Saturn comes first in the list than Mars. He pointed out that Titan has a dense nitrogen-methane atmosphere while the Mars has nearly no atmosphere. Additionally, Titan has lakes of liquid hydrocarbons (largely ethane and methane). Huygens probe revealed during its touched down in 2005 that Titan has plenty of complex chemistry going on.

If life is only based on carbon chemistry, the capability of Titan to handle life would be at least vaguely familiar. However, researchers likewise speculated on the possible life forms based on silicon, which is also part of the PHI. Schulze-Makuch said that planet with complex silicon chemistry is not rank high using PHI because silicon is not chemically versatile as carbon. Nevertheless, he and his colleagues do not want to prematurely rule out any possibility.

Aliens Artifacts in Finding Evidence of Other Civilizations outside Earth


A report from scientists Jacob Haqq-Misra and Ravi Kumar Kopparapu states that any remote unpiloted exploratory probes of extraterrestrial origin would seemingly stay overlooked considering the vastness of space and the limited searchers so far.

Enrico Fermi formulated the Fermi paradox which questions as to why mankind did not find any evidences of intelligent life given the idea that intelligent life is common. Answers could include that life is uncommon, intelligent cultures might destroy themselves, other civilizations are capable of sending unpiloted probes to sneak quietly the human civilization.

Haqq-Misra and Kopparapu said that there is a possibility that extraterrestrial artifacts are there in the Solar System but humankind overlooked at them because of lack of sufficient research. They used a probabilistic method to know if humankind has done enough in their search of extraterrestrial artifacts. The analysis is based on giving answers to the question if the recent researchers by mankind are enough to find extraterrestrial objects in the Solar System.

They consider the Solar System as a fixed volume and analyze the percentages of that volume that would need to be properly explored utilizing a potential discovery which is enough in detecting these probes with the assumption that the probes are not intentionally camouflaged.

The two then formulate an equation that can be applied to the Solar System’s portion of the volume and identify whether ample searching has been carried out to make humankind conclude that there no extraterrestrial objects within that volume.

The two conclude that at this moment in time, conducted searchers are still not enough to detect alien artifacts in the Solar System.

Alien Planet Found Accounted to Over 700 in Total


Astronomers have already discovered over 700 alien planets twenty years after finding the first world outside our solar system.

According to Extrasolar Planets Encyclopedia, the total exoplanets found stands at 702 in number as of November 18, 2011. The data was compiled by Paris-Meudon Observatory astrobiologist Jean Schneider.

The list by Schneider is one of two major alien-world trackers available. The otherone is called “PlanetQuest: New Worlds Atlas” by Jet Propulsion Laboratory of NASA which has a recent tally that stands at 687. The difference in number plays up the detection and confirmation’s uncertainties involved.

Nevertheless, both data have increasing number of exoplanets discovered and it is expected that both numbers will go up in the near future to perhaps thousands of new extraterrestrial planets.

Alien world was first discovered in 1992 by astronomers when they found two planets orbiting a rotating neutron star or pulsar around 1,000 light-years from planet Earth and was confirmed in 1995.
Since then, the number has been increasing dramatically and in November 2010 the count went up to 500. Two months later, the tally climbed to 600 as the European Southern Observatory declared 50 newly discovered 50 planets which include the “super-Earth” that thought to be capable of handling life.

The number of breakthrough only keeps on going up as researchers extend their efforts and techniques in hunting more extraterrestrial planets.

One advanced instrument in particular could triple the number of discovered alien planets. Since the launching of Kepler space telescope of NASA in 2009, it has distinguished 1,235 planet candidates. As of today, only 25 of them have been confirmed but Kepler researchers’ data indicates that about 80 percent will end up part of alien planets.

Scientists say that the increasing numbers of discoveries are somewhat interesting but the search for extraterrestrial planets is not just about the increase in tally but rather a search for better understanding of alien worlds.

The discoveries are diverse; from alien planets which are as light and airy as Styrofoam to as dense as iron. Astronomers have confirmed various planets where liquid water and perhaps life could exist.
